Installation location
Choose a firm, level surface on which to place the unit. To pre-
vent damage or accidents avoid the following locations :
●
Locations without proper air circulation or with high levels of
dust or humidity
●
Locations exposed to direct sunlight
●
Locations close to heating appliances
●
Locations which can get very cold
●
Locations which are not level or are subject to vibrations.
Never stack audio components directly on top of each other.
Keep the unit away from tuners, TV sets, and VCRs
●
If placed close to such equipment, noise and picture dis-
tortion may occur (especially when placed close to a room
antenna).
●
Route the power cord of this unit and input/output cables
at a distance from any antenna cables.
■
Never view the laser beam directly.
This unit contains a laser that can cause eye injury.
■Turn all components off before making any connections.
When the RCA-type phono plugs of ordinary audio cables are
connected or disconnected, the negative and positive leads do
not make or break contact simultaneously. This momentarily non-
grounded condition causes a current surge (heard as a loud
pop noise), which may damage the speakers. To prevent this,
be sure to switch off the power before making input or output
connections.
■
Verify that all connections are established correctly before
turning on the POWER switch.
■
Always turn the power off before inserting or removing any
option boards.
■
Do not turn the POWER switch off and immediately on again.
(Wait at least 10 seconds.)
■
Disconnect the power cord from the AC outlet if the unit is
not be used for an extended period of time.
■
Do not use contact refreshers or other chemicals on the in-
put and output jacks and the speaker terminals, since these
can cause aging in resin parts and lead to damage.
■
Listening level
The frequency response of SACDs extends into the ultra high
frequency range beyond the threshold of human hearing. If the
volume is turned up while no signal is heard, noise or sudden
loud passages can cause damage to the amplifier or loudspeak-
ers. Always turn down the volume to safe levels.
■
HS-Link cable connection
Use HS-Link cable to input the signal from the DP-77 to an audio
component equipped with an HS-Link connector.
●
Use only HS-Link cable from Accuphase.
●
Take care not to accidentally connect the unit to a computer
LAN or similar, using the same RJ-45 connector. This may
result in fatal damage to either equipment.
■
Condensation on pickup lens
In the following cases, moisture condensation may form on the
optical lens of the unit:
●
Immediately after the room is heated.
●
When the unit is placed in an extremely damp or humid room.
●
When the unit is moved from a cold to a warm location.

Disc handling
〜
If condensation occurs
The laser pickup cannot read the signals on the disc and the
player does not operate correctly or not at all.
In such a case, remove the disc and leave the unit turned on
for about one hour. This allows the moisture to evaporate and
will restore normal operation.
●
If required, clean the unit carefully with a soft, slightly moist-
ened cloth, and then wipe it dry. Never use solvents or abra-
sive cleaning agents, since these will damage the finish.
●
Do not use contact refreshers or other chemicals on the in-
put and output jacks and the speaker terminals, since these
can cause aging in resin parts and lead to damage.
Usage Precautions
PRECAUTIONS
●
Protect discs from direct sunlight, high temperatures,
and high levels of humidity.
●
After playback, always return the discs to their boxes.
●
Take care not to leave fingerprints or smudges on the re-
corded (shiny) side of the disc, since these can lead to a
degradation in sound quality.
●
If a disc has become dirty, wipe it lightly with a soft cloth,
moving from the center outward in a radial pattern.
●
Do not use any cleaners, solvents or antistatic sprays, since
these can damage the disc.
